I would have been fine if they had a different name from the start but im also fine with a 3. The game follows what is happening in the events of BG after 1&2 and the expanded world. This makes a lot more sense to me that what was going to happen with Black Isles planned BG3.
I dont see the name hurting sales other than review bombing but my understanding is that steam blocks refunded games from affecting the number so that will be a nice $60 review bomb or MW2 boycott situation. Meta critic also is kinda known for people not paying attention to users if the narrative is people are review bombing. Even more than that it will bring in a TON of new people. i have friends in my D&D groups super excited for this who were hesitant it would be like old IE games.
I understand the criticism to and extent (i think most of the screaming is by people who define BG by RTwP and are looking for anything to hate) but its also WAY over blown to the point where its really starting to seem like some people are going to need therapy/ have already talked about it with their therapist. I have loved some of the constructive criticism discussions ive had with people on a variety of forums and even got a few people interested who were sad it wasnt going to be what they expected and ive found certain places dying down to the point where its the same few people screaming and not a majority up roar which hopefully means it will die down and conversation will be able to be had and some issues can be addressed in EA
